Product Overview

The Current Transformers (for Motor Protection) are an important part of providing electronic safety solutions in your B2B manufacturing facility. The current transformer for motor protection is precisely designed to protect HVAC/R, AC Motors, and Air Compressors from electrical failures by detecting electrical faults in these products. The Current Transformers are made of Flame Retardant UL 94-V0 PBT or ABS enclosure, Epoxy encapsulated for durability in a harsh industrial working environment. As a reliable protective current transformer, the device has superior electrical isolation of 2500V AC, and has a 5000V surge withstand capability, meeting the most stringent international safety standards.

The protection current transformer designed for motor protection operates reliably at 50-400Hz from -25°C to +55°C, and provide stable operation throughout the entire range of operational limits. The current transformer meets Class 0.2/0.5 IEC 60044-1 Standards of Accuracy, therefore providing accurate data used in building energy management systems. The current transformer for motor protection has been uniquely designed to accommodate high inrush currents; it can accommodate 10x rated load for 2 seconds without causing a false trip during motor start-up.

The current transformers for motor protection are available in over 10 standard sizes, various chassis mount or DIN rail mount configurations, allowing for simple purchase and integration into your current manufacturing environment. Additionally, the protection current transformer for motor provides RoHS and CE Certifications as proof of quality and environmental responsibility. Purchase YuanXing’s protective current transformer for electric motors for superior monitoring of electric motors and reliable detection of electric motor faults in your manufacturing infrastructure.
